I received this last night. I hooked it up running the speaker level inputs from an SMSL SA50 then ran the speaker outs to a pair of Micca MB42c. I have not officially found a place for this sub woofer or used it enough to break it in. Because audio is subjective I'll describe my experience in practical terms.

Being that this is still really new to me I will say that it IS big and powerful. The bass will more than fill the space and is not easily contained. If you have neighbors or people that need quiet, you will probably have difficulty using this sub woofer to its fullest without conflict. In an apartment, it won't matter. This will ruin your neighbors quality of life. They will hate you for your obnoxious bass. The most wonderful things you have heard suddenly become the most hated thing if you are on the other side of the wall and are forced to hear it.

If you have neighbors that are away and have windows of opportunity, this sub woofer is amazing. I am not a "loud volume" user. I like room filling sounds and clarity. At low levels, this sub woofer delivers that with faint sound leakage that can be heard out to the curb. I estimate I could hear rumbles 20-30 feet from the house. It should not be enough to annoy anyone but I feel like I should be vigilant to keep peace with my good neighbors.

This is *probably* more bass than a home theater needs but it's everything you want a sub woofer to be. It's loud. It's deep. It's tight. It's powerful. I have it adjusted to "tuck in" right where my soundbar alternative leaves off and picks up all that meaty detail. It's completely ridiculous unless you get it under control. So far, I love it. I am ready to apologize and make amends with my neighbors if need be.

Yes, it's like that.

I've had this sub for a year now and I must say it works great. I have a Polk PSW-505 as well and in comparison they are very close. I honestly cannot choose which one is better. I play the F12 loud and have for many many hours and have had zero problems. It has never overheated or any issues at all. I recommend this for sure. It is very loud and clean. I like the way it looks too.

I spent hours and hours reading all over about subwoofers in this price/spec range. I finally bought this one and could not be happier. Although i have only had it for a short while, it has been used extensively in that time frame for music and movies and has done very well. We put it through it's paces for a NYE party, that's for sure. My living room is under 400 sq feet, so I cannot speak of how it would do in a larger room, but I suspect that in a larger it would still do very well, considering how it sounds from my kitchen, which is adjacent to my LR.

Right now I'm going with 5 stars. The unit feels a little well, cheap. It looks good enough once sitting in the corner it's just not Polk/Yamaha quality as far as the case it concerned.

Now let's talk about the sound for a min here. I'm not audiofile (would like to be) but I would say it's all but perfect for my system.
I have a home theater downstairs with a Yamaha Amp, Front and center channels are Polk, surround speakers are all Yamaha. In the front right corner is where I placed this sub, I also am running a 10" KLH sub that is positioned behind the seating so we are getting a really good experience.
The BIC sub really hits the lows well. I started Gone in 60 Seconds and it sounded great, no distortion just nice and clear bass.

After a lot of research -- reading forums, reading Amazon reviews, talking to friends -- I picked up the F12. I am extremely happy with my decision. This sub nicely complements my BIC DV-62CLRS center channel and BIC DV62si bookshelf speakers, with plenty of capacity if I decide to upgrade any other components.

I'm rediscovering my favorite movies because this thing delivers an entirely new viewing experience. If you're looking for an excellent budget sub, I highly recommend the F12.
